The growing use of public blockchain-based virtual cryptocurrency calls for secure management of blockchain account information managed through cryptocurrency wallet programs. The previously proposed wallet program has high security in terms of managing an account's private key, but low security in managing an account's recovery phrase. Therefore, in this paper, we propose a safe management system of blockchain account recovery string based on the new user authentication method using the user's mobile device information and OTP technique to overcome the problem of the existing account recovery string management method. It also conducts an analysis of the proposed blockchain account recovery string management system based on the expected behavior scenario.

In the study of Guunmong, which is one of the representative classical $17^{th}$ century novels of the Joseon Dynasty, interpretations through The Book of Change(Juyeok) have recently emerged. It is necessary to more concretely investigate the themes of the research. The writer Kim man-jung wrote the work in an exile situation. In that time he composed a poem using Chinese letters with meaning connected to The book of Change. In particular, the discourse of Bok-gwae(復卦, ䷗) concentrating on the meaning of recovery might be a basis to construct the inner world of the work. The sentence of 'Bok goes well' in The Book of Change suitably match up with the hero's life in Guunmong. In addition the sentences of 'There is no illness in going and coming. So it will be no faults if friends arriver' can be applied to the meeting between the hero and heroines of Guunmong. The general declarations of The Book of Change are appropriate for explaining the contents of Guunmong. There are six Hyos that make up Gwae. The Hyos, from the first one at the bottom to the fifth one up above, connect to the characters of Guunmong. The phrase of 'Not going far away' regarding to the first Yang Hyo can be connected to Yang So-yu, hero of Guunmong. The phrase of 'Recovering beautifully' with regard to the second Eum Hyo can also be realized in the life of Jeong Gyeong-pae and Ga Chunun, two heroines of the work. The phrase of 'Danger owing to frequently recovering' regarding the third Eum Hyo can be applied to the position of Gye Seom-weol and Jeok Gyeong-hong. The phrase of 'Going middle with recovering alone' regarding the forth Eum Hyo can be matched with Sim Yo-yeon and Baek Reung-pa. The phrase of 'No regrets during an intense recovery' with regard to the fifth Eum Hyo is applicable to Yi So-hwa and Jin Chae-bong. The phrase of 'Boding of a confused recovering' regarding the sixth Eum Hyo is related to the writer's situation. The boding of confused recovering is owing to anti-royal road. The contrast between the royal road and the anti-royal road reflects Confucianism and Buddhism, dream and reality, and Yang So-yu in a dream and Seong Jin, who is same hero, in reality. Moreover, the structure of Guunmong which is organized in the form of reality-dream-reality, has a basis in this contrast. Considering these relationships, we can say the classical novel Guunmong is a fable of Bok-gwae. The work is a hopeful narration of an effective recovery that the writer anticipated in exile.

Zero anaphora occurs frequently in Korean complex sentences, and it makes the interpretation of sentences difficult. This paper proposes splitting algorithms and zero anaphora recovery rules for the purpose of handling zero anaphora, and also presents a resolution methodology. The paper covers quotations, conjunctive sentences and embedded sentences out of the complex sentences shown in the newspaper articles, with an exclusion of embedded sentences of auxiliary verb. We manage the quotations using the equivalent noun phrase deletion rule according to subject person constraint, the nominalized embedded sentences using the equivalent noun phrase deletion rule, the adnominal embedded sentences using the relative noun phrase deletion rule and the conjunctive sentences using the conjunction reduction rule in reverse. The classified table of the endings which relate to a formation of the complex sentences is used for splitting the complex sentences, and the syntactic rules, applied when being omitted, are used in reverse for recovering zero anaphora. The presented rule showed the result of 83.53% in perfect resolution and 11.52% in partial resolution.

Generally, a speaker structures utterances very clearly by grouping words into phrases. This facilitates the listener's recovery of the meaning of the utterance and the speaker's intention. To this purpose, a speaker uses, among other things, prosodic information such as intonation pause, duration, intensity, etc. The research described here is concerned with the relationship between the strength of prosodic boundaries in spoken utterances as perceived by untrained listeners(Perceptual boundary strength, PBS)-In this paper, the preceptual boundary strength is used as the same meaning of the prosodic boundary strength-and prosodic information. We made a rule determinating the prosodic boundaries and verified the usefulness of the prosodic phrase as a recognition unit. Experiments results showed that the performance of speech recognition(SR) is improved in aspect of recognition rate and time compared with that using sentences as recognition unit. In the future we will suggest the methods that estimate more appropriate boundaries and study more various methods of prosody assisted SR.

Alberti's De re aedificatoria is the earliest case in the history of Italian Renaissance architectural treatises dealing with recovery of antiquity through textual and archaeological pursuits. The key source of the Renaissance theoreticians was Vitruvius' De architectura. However, Alberti was keenly aware of inaccuracy and Hellenization of Latinity in this classical text, and tried to compensate them in his own treatise. Furthermore he claimed a reformed discipline of the architects as well as the patrons, and prescribed how future buildings and cities should be built, based on the proper authority of ancient architecture in proper and intelligible Latin. Such an adaptation of classical usage in order to reestablish a modern norm preceded in his earlier work Momus, a satire on the contemporary Italian society of his own by following the model of Lucian. Alberti's suggestion of proper government in Momus's phrase was expanded in De re aedificatoria, for he consider the buildings are subject to the rules of morality and public interests. He proclaimed that the nature of beauty is the reasoned harmony of every part within a body, and architectural beauty also lies on the harmonized arrangement of all the elements within an individual building and of all individual buildings and facilities within a city. For the architects to execute this task, he formulated the concept of lineanenta, the form derived from the mind in order to prescribe the proper place, numbers, scale, and orders for whole building structure. It is the future oriented city-plans and building designs to serve the public interest and the good of all the individual citizens who make up the City-State that Alberti pursued in his treatise.
